SP431

High Voltage Adjustable Precision Shunt Regulators

DESCRIPTION

The SP431 is high-voltage three-terminal

adjustable voltage references, with specified

thermal stability over applicable industrial and

commercial temperature ranges. Output voltage

can be set to any value between V

REF

(2.5V) and

36V with two external resistors. These devices

have a typical output impedance of 0.25Ω. Active

output circuitry provides a very sharp turn-on

characteristic, making the SP431 excellent

replacements for low-voltage Zener diodes in

many applications, including onboard regulation

and adjustable power supplies.
